During an incident response activity, what critical process ensures that digital evidence is preserved from the point of collection until it is presented in court?
The correct process for ensuring that digital evidence remains unaltered and is documented properly from the time of collection to its presentation in court is the 'chain of custody'. It involves tracking the movement and handling of the evidence through a detailed log. Validating data integrity refers to checking that the data has not been tampered with but does not involve the detailed documentation of handling. Preservation refers to protecting the evidence but not the detailed tracking of its movement, and legal hold is a directive to preserve all forms of relevant information once litigation is anticipated but it lacks the tracking aspect of chain of custody.
